SHELL-EJECTOR FOR FIREARMS.

invention appertains to make and use the same. v

My present invention relates to improvements in the shell-ejectormechanism, the obj ects being to render the mechanism substantial,durable, and efficient for use and economical for manufacture and toprovide an ejector mechanism comprising means for primarily positivelystarting the shell from its seated position, in combination with meansfor then automatically throwing said shell completely out and away fromthe chamber,

said mechanism being constructed and organized for operation in themanner more fully hereinafter set forth.

Another object is to provide an automatic ejecting device with a rockingejector-catchhaving an arm and lug that work in conjunction with astop-shoulder on the frame for tripping the ejector, as more fullyhereinafter explained.

These objects I attain by the mechanism illustrated in the drawings,wherein- Figure l is a sectional view of a gun embodyin g my invention,the parts being shown atthe position occupied after the positivestarting of the ejector, but immediately preceding the automatic finalejective action. Fig. 2 is a transverse section through the frame andbarrel, showing the form of the ejector-catch and the lug or shoulderforactuating the same. Fig. 3 is a sectional plan showing the top of theejector and jointscrew mechanisms. Fig. 4 is a side view of thejoint-screw arm, and Fig 5 a separate plan view of the ejector-catch andits spring.

In referring to the drawings, A indicates the stock-frame, of suitableor well-known form.

B denotes the barrel, having the j oint-block B fixed on its under sideand adapted to fit within the hollow of the frame and hinged or pivotedtherein by the joint screw or pin O for breakdown or forwardly-tiltingaction of the barrel, as illustrated. Said joint-pin 0 passes throughand movably fits a transverse hole formed complete within the jointblock13, near the fore end thereof, said hole coinciding with the openings inthe sides of the frame, one of which latter is threaded to receive thescrew-thread at the end of the joint-pin when the parts are assembled.

The barrel-catch E and top lever E for operating the same may be ofwell-known or any suitable construction.

D indicates the ejector-bar, arranged within a longitudinal bore in thejoint-block B and having the usual head cl for engaging the rim of thecartridge-shell, also provided with the backwardly pressing spring G,coiled about its spindle portion D within the'bore. Theinner endof thelongitudinal bore or ejector-way is disposed at an overlying position inrelation to the transverse hole and partially intersected therewith, thetop side of the transverse hole being about half-way up in thelongitudinal bore. The spring-supporting spindle D can be an integralpart of the main bar D or made as a separate piece abutting against theend thereof, as per Fig. 1.

I indicates a rocking catch disposed transversely in the joint-block Bbeneath the ejector-bar D, which is recessed on its under side andprovided at an intermediate position in the top of the recess with anoffsetlug n or stop-notch that is engaged by the angle of said rockingcatch, the face of which is cut away or flattened, as shown at 3, sothat the rocking of the catch-piece will release the ejector. The catchdevice is secured in the joint-block by acircular nut 4 on one end, andits other end is provided with forwardly and downwardly projecting armI, that works in a suitable recess formed in the side of the block. Thelower end ofthe arm is furnished with a transversely-disposed pin 1",one end of which is pressed by a spring J for keeping the catch normallyat interlocked position, while the other end of said pin projects withina recess a, formed in the side of the frame, and acts in conjunctionwith a horizontal shoulder a at the top of said recess for moving thearm and tripping the catch, thereby releasing the ejector when thebarrel is tilted to a given degree or sufficiently to carry the pin iagainst the shoulder aa slightly greater tilt than that indicated inFig. 1. The shoulder a has a cut-away space at to .permit separation ofthe frame and barrel parts when the joint-screw has been removed and thebarrel drawn somewhat forward to bring the pin 9; into line with thecut-away.

The joint-screw C is-made with'a recess in the side thereof, forming atits top an upright lug or shoulder r, disposed across the ejectorway andagainst which the end of the ejectorspindle contacts in such manner thatwhen the rear end of the barrel rises from the recoil-plate to theposition indicated in full lines, Fig. 1, the ejector D will bepositively forced backward for a short distance and with sufiicientpower to start the shell S from the chamber, (see dotted lines, Fig. 1,)overcomin'g any adhesive tendencyor sticking of the shell and partiallyfreeing it from its seat,'so that the resilience of the ejector-springwill meet no excessive resistance in throwing out the shell when theautomatic ejector is subsequently brought into action. The jointscrewis'th'readed into one side of the frame at t and i's'provided with anarm C at its head end, theinner side of said arm fitting againsttheouter side of the frame when 'the screw is set'home. A latch-fingerfis arranged in the slotted end of the arm, pivoted, as at h, and adaptedto closedown with its end latching into a nick 5, formed in the frame,as indicated in Fig. 3, for. retaining the joint-screw against anytendency for its unscrewing by reason of the pressure of the ejector onthe lug r. The latch-finger f is adapted to'bei swung outward, asindicated by dotted lines, Fig. '3, and there serve as a crank-handlefor turningthe joint-screw in and out when desired. The'recess min theejector-bar forward ofthe offsetnis made of sufficient length to permitthis positive movement before the catchI takeselfect on said .oifset. Inthe operation when the barrel'is unlatched and tilted forward thefirstportion ofthe'tilt movement causes the ejector D to be slowly andpositively forced outward by the spindle impinging against the lug r,was

to start the shell from the chamber however firmly itmay be wedgedtherein. Then as the further tilting movement brings'the-pin i intocontact with the shoulder a the catch I is rocked away from the offset nand the spring J automatically drives back the ejector D, easily andeffectively ejecting the shell and throwing itfree and clear from thebreech of the gun, thus insuring complete ejective action and. obviatingany liabilityof the shells sticking in the v chamber with a resistancethat would exceed the power of the ejectorspring. When the barrel istilted back to its regular position, (see dotted lines in Fig. 1,) theejector devices are caused to assume their normal set position by theejector-head working against the face of the recoil-block.

I claim as my invention and desire to secure by Letters Patent- 1. In abreech-loading firearm in which the barrel is hinged for breakdownaction, the

combination, as described, of the barrel-hinging joint-block providedwith a transverse hole therethrough for the joint-pin, and .alongitudinal ejector way-bore overlying and partially intersecting withsaid transverse hole, a'joint-pin 'having'an upright shoulder, disposedacross the 'ejector-*Way,.and'an external 'arni provided with a lockingdevice, the ejector-bar monntedwithin the ejectorway with its endabutting on said shoulder,

said ejector-bar provided with *anunderre cess fitted with anintermediate 'oifset, the ejector-actuating spring, a retaining-catchwithin said recess,against which saidoffset engages subsequent to aprimary movement of the ejector, and the means for retracting said catchto release'theejector foraction by said spring, substantially as setforth.
